TEMPORARY BINDER OR LOOSE-SHEET HOLDER.

Specification of Letters Patent.

Patented Sept. 15, 1914.

Application filed. December 10, 1913. Serial No. 805,798.

This invention relates to improvements in temporary binders or loose sheet holders.

The main objects of this invention are :v

First, to provide in a temporary binder or loose sheet holder an improved ratchet adjusting mechanism. Second, to provide an improved temporary binder or loose sheet holder of the post type which may be very quickly and easily adjusted to secure `the leaves or to permit the removal thereof. Third, to provide in a temporary binder or loose sheet holder in which the binder parts are made mainly of metal covered with flexible fabric, an improved means of securing the fabric. Fourth, to provide an improved temporary binder or loose sheet holder which is very economical and simple in structure, and at the same time very durable.

Further objects, and objects relating to structural details, will definitely appear from the detailed description to follow.

I accomplish the objects of my invention by the devices and means described in the following specification.

The invention is clearly defined and pointed out in the claims.

A structure which is a preferred embodiment of my invention is clearly illustrated in the accompanying drawing, forming a part of this specification, in which Figure I is a. detail inside view with the covers extended. Fig. II is a detail section through the adjusting mechanism on a line corresponding to line 2-2 of Fig. I. Fig. III is a detail section on a line corresponding to line 3-3 of Fig. I. Fig. IV is a den tail section of the adjusting mechanism on a line corresponding to line 44 of Fig. II. Fig. V is a perspective view of the spring aawls and their operating lever. Eig. VI is a horizontal section on a line corresponding to line 6- 6 of Fig. II. Fig. VII is a plan view of the blank from which the support member is formed. Fig. VIII is a plan view of one of the members 29.

In the drawing similar reference characters refer to similar parts throughout the several views, and the sectional views are Aform the back of the binder.

taken looking in the direction of the little arrows at the ends of the section lines.

Referring to the drawing, the structure illustrated is provided with a pair of covers 1 and 2. rIhe binding members 3 and 4 are secured to the covers 1 and 2 respectively by means of the flexible hinge connection 5. The binding members 3 and 4 are provided with inwardly projecting over-lapping members or portions 6 and 7 respectively which The binding members are provided with telescoping posts 8 and 9 respectively. The binding members are, in practice, formed of sheet metal with a suitable covering 10 of fabric or leather as may be desired. The binding member 4 is provided with double ratchet members 11 mounted at each end thereof.

lvfo-unted at the ends of the binding member 3 to receive the ratchet members 11 are housing-like supports 12 formed of sheet metal blanks 13, shownin Eig. VII. These sheet metal blanks 13 are folded into rectan lgular housings as shown, ythe folding lines being indicated by dotted lines. The side walls of the supports are shouldered at 14` while the lower ends of the end walls are offset inwardly at 15 to lthese side wall shoulders. The end walls are provided with securing tongues 16 arranged through slots 17 in the member 3 and folded against the outer side thereof, as shown in Fig. II, thus Yrigidly mounting the members 12 upon the binding member 3.

The spring pawls 18 and 19 are provided with shoulders 2O at their lower ends and are arranged in the Vsupport with their lower ends between the shoulders 14 of the side walls and the offsets 15 of said end walls, the upper edges of their shoulders 20 engaging the lower edges of the side walls, see Fig. VI. The springs are thus supported within the supports 12 with their upper ends free to coact with the teeth of the ratchet members 11. The upper ends of the springs are turned inwardly to provide engaging portions 2l. The end wall of the support having free edge is out away at 22 to provide a. slot for the lever 23. The lever 23 is arranged through this slot and mounted on the outer side wall of the sup-- port by means of the pivot 24. The lever is provided with a cam head 25 disposed between the pawls and having inturned lugs 26 and 27 coacting therewith, so that when the lever is swung on its pivot to one position the pawls are separated, releasing the ratchet, and when moved to the other position the pawls are free to engage the ratchet. The lever is yieldably retained in both positions by the spring pawls. The pawl 18 is cut away at one side, as at 28, to accommodate the lever.

To facilitate the secuiing of the flexible covering 10, flexible metal tongues 29 are provided. These metal tongues are slotted at 30 to receive the securing tongues 16 of the members 12, and are supported by these members so as to project outwardly, as shown by dotted line in Fig. IV. The end edges of the covering 10 are folded over these flexible tongues, and the tongues are then folded against the sides of the members 12, thereby effectively securing the covering at this point. lith the parts thus arranged, the binder is adjusted to clamp the leaves merely by introducing the ratchet v 'lower ends of its end walls being offset inmembers into the supporting members 1:2 and pushing the same down to clamping position, the levers being thrown into the position shown in Fig. Il, to allow the pawls to act. To releasev the same the levers are thrown down, which releases the pawls, and the ratchet members can then be freely withdrawn. rlhe levers are arranged through the front sides of the members 12 so as to be conveniently grasped and, at the same time, are entirely out of the way and are not likely to be accidentally shifted from one position to another.

l have illustrated and chescribed my improved binder in detail in a simple and effective embodiment. l have not attempted to illustrate or describe certain modifications which l contemplate, as I believe the disclosure made will enable those skilled iii the art to which this invention relates to embody or adapt the saine as may be desired.
